G40-45 won’t boot up

My G40-45 will not bootup. When I turn it on it shows the Lenovo symbol then after a few seconds the revolving circle. It keeps doing this for a long time but never actually opens to Windows or main screen. It has just started happening. I have tried removing the battery and pushing power button for 30 seconds then replace battery and the same battest and power lights come on. I am not sure what to do. Thanks.

Re: G40-45 won’t boot up

Hi leeleetoyou,


Welcome to the Community Forums.


You can start with your data if you need to take out from the harddrive.


I usually pullout the drive and slave it on another machine either directly or place it on a harddrive enclosure to back up. This would also allow me to test if the harddrive would be detected and run hardware test with it.


If it pass the test then I we would know that the hardware are ok and leaves us with probable Windows system error that advance repair option can be done else do factory reset using the Novo button as last option.


Update us how it goes best on your end so we can set how to proceed further.
